Prop Tart 

An old theatrical term to describe a Props Mistress or a female prop person in a theatrical production. Since assumed by women (and men) doing a similar job in film and other related fields. A theatrical property, commonly referred to as a prop, is an object used on stage by actors to further the plot or story line of a theatrical production.

I was hanging around backstage with the Mary, the prop tart.
